ELECTROKINETICS, INC. INSITU BIO REMEDIATION BY ELECTROKINETIC INJECTION EMERGING TECHNOLOGY SUMMARY
Parker*, R A. ELECTROKINETICS, INC. INSITU BIO REMEDIATION BY ELECTROKINETIC INJECTION EMERGING TECHNOLOGY SUMMARY. U.S. Environmental Protection Agency, Washington, DC, EPA/540/SR-00/503, 2000.
Electrokinetics, Inc. through a cooperative agreement with USEPA's NRMRL conducted a laboratory evaluation of electrokinetic transport as a means to enhance in-situ bioremediation of trichloroethene (TCE). Four critical aspects of enhancing bioremediation by electrokinetic injection were investigated: 1) determination of the efficiency of injection of representative nutrient ions into both homogeneous and heterogeneous soil masses with high and low hydraulic permeabilities; 2) shake flask studies to confirm that the injectable ions are capable of enhancing TCE degradation and to determine the kinetic parameters; 3) bench-scale studies to optimize injection and TCE degradation mechanisms; and 4) a prototype study to injkect ions into a one-meter long soil mass and to compare TCE degradation rates versus a control.
